Configuring Voice Channel Redundancy
Using VAD and Configuring Voice Channel Utilization
Voice Connections
The voice commands apply to setting up and configuring, and statistical reporting for voice connections (including FAX). In addition to the command descriptions, this chapter describes how to add a voice connection, configure card redundancy, and optimize the use of voice activity detection (VAD). A list of the commands that let you modify most characteristics of voice and data connections also appears at the front of the chapter. Use this list as a guideline for building voice service.
Voice connections exist as ports on circuit lines that are supported by a Channelized Voice Module (CVM) or Universal Voice Module (UVM) in an IGX node. The back card for the CDP or CVM is either a BC-T1, BC-E1, or BC-J1. For the UVM, the back card is either a BC-UVI-2T1EC, a BC-UVI-2J1EC, or BC-UVI-2E1EC.
Setting Up a Voice Connection
The following steps describe how to set up a voice connection.
Step 1
Configure the voice channel at each end of the connection. The associated commands are:
Step 2
Configuring Voice Channel Redundancy
You can configure voice cards for redundancy by installing two identical card sets in adjacent slots and connecting them to the CPE through a Y-cable. Configure redundancy by using addyred. Note that a switch to a standby UVM that has active CAS-switching causes the loss of all call states.
Using VAD and Configuring Voice Channel Utilization
The bandwidth savings you gain by using VAD are less than optimal if you do not set the utilization of the voice channels to a reasonable value. To configure the utilization, use the cnfchutl command.
Summary of Commands
Table 6-1 shows the command name and starting page for the description of each command.
addcon
Establishes the channel connections between nodes in the network. You can add voice connections to any slot that has a CDP, UVM, or CVM. Before you add a connection, determine its compression type.
If you plan for a port on a UVM to carry more than 16 channels with LDCELP or the G.729 version of CACELP, you must have a second, connected UVM and configure the resultant pair of UVMs for passthrough operation. If you attempt to add more than 16 LDCELP or G.729 channels, the system reports any excess connections as being failed connections after addcon execution finishes. Furthermore, if you execute dspcon, the status display for the excess connections shows "ConnRJ" (connection rejected). Refer to the cnflnpass description in this chapter and the UVM description in the Cisco IGX Reference for a description of passthrough.
After you have established passthrough for a pair of UVM card sets, the system does not allow duplication of channel numbers when you add connections. For example, if you add 7.1.1-16, the node does not allow you to add 8.1.1-8 if you have linked the UVMs by using cnflnpass. Instead, you would add 8.1.17-24.
A UVM with Model B or higher firmware supports CAS switching. Before you can add connections in a network with CAS switching, you must configure the UVM for this feature with the cnfcassw command. Note that, for CAS switching, you use addcon to add the signaling channels at the near and far end in the format slot.port.24 on a T1 line and slot.port.16 on an E1 line. Also, the connection type for these signaling channels is "t." If you specify D-channel compression, the connection type is "td." See the description of cnfcassw in the "Setting Up Lines" chapter or, for a more detailed description, the manual titled Cisco VNS (Voice Network Switching) Installation and Operation.
When adding a range of channels, you do not have to specify the full channel set at the near-end. You may specify only the first channel in the set. For example, to connect channels 13.1-10 at alpha to channels 12.5-14 at beta, you could enter "addcon 13.1-10 beta 12.5." In this example, channel 13.1 is connected to channel 12.5, and channel 13.2 is connected to channel 12.6, and so on.
Connections are added with a default class of service (COS). The value of COS is the number of seconds that the node waits before it reroutes the connection after a failure. The COS applies to various types of connections other than voice and therefore is described elsewhere (see the cnfcos description in the "Optimizing Traffic Routing and Bandwidth" chapter).
Table 6-2 and Table 6-3 describe what you enter for the type parameter for each rate and compression variable.
The difference between a PCM (p) connection and a transparent (t) or transparent D-compression (td) connection is that the D4 frame signaling bits are identified and processed as signaling information with PCM connections. PCM connections permit gain adjustment to be applied to the connection. Transparent connections treat all bits, including signaling bits, as data bits and disables any gain adjustment conversion that you may have specified.
The number in the type field indicates the ADPCM rates in Kbps. The "z" suffix indicates that 00 code level is used. Type a16 or c16 uses only 01, 10, and 11 binary codes to avoid long strings of zeros. Type a16z and c16z connections use the 00 code and are automatically configured to avoid ZCS lines (*Z).

addcon 7.2 beta 8.2 v
Description
Add a "v" type voice connection. This command connects channel 7.2 on node alpha to channel 8.2 on node beta. A prompt appears asking you to confirm the proposed connections.
Connection type is "v," Class of Service (COS) is "2," compression is VAD, and ownership is local. For an explanation of COS, see the cnfcos description in the " Optimizing Traffic Routing and Bandwidth" chapter. Because you are entering the addcon command at node alpha, the node alpha is the owner of the connection.

Table 6-5 addcon—Parameters
local channel
Specifies the local channel or set of channels to add. Right-angle brackets indicate a range of channels. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM, as follows:
For a CDP or CVM, the format for channel specification is slot.chan[-chan].
For a UVM, the format for channel specification is slot.line.chan[-chan]. Refer to the Cisco IGX Reference for a description of the UVM's lines. Note that, if you are using CAS switching with Model B firmware, line must be 1.
node
Specifies the name of the node at the other end of the connection. For a DAX connection (where channels on a node are connected to channels on the same node), use the local node name.
remote channel
Specifies the remote channel or set of channels to connect. Brackets indicate that a range of channels can be specified. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM. For a CDP or CVM, the format for channel specification is slot.chan[-chan]. For UVM, the format for channel specification is slot.line.chan[-chan].
Access devices such as the Cisco 3800 use the following format for the remote channel specification: <slot.port> <access_device_connection_ID>
where slot is the slot number of the FTC or FTM card, port is the port number, and access_device_connection_ID is in the range 1-252.
type
Specifies the voice connection type. Refer to Table 6-1 or Table 6-2 for voice connection types and compression.
For connections to an access device such as the Cisco 3810, type can be one of the following: 24 Kbps or 32 Kbps ADPCM, LDCELP, or CACELP.
cnfchadv
Enables the adaptive voice (ADV) feature for individual channels. ADV must also be enabled at each node that terminates the connection. The channel-specific cnfchadv has no effect at nodes that do not support ADV enabled.
If the ADV feature is enabled for a channel with a "c" or "v" connections, VAD is automatically disabled on that channel when trunk bandwidth is available and enabled when trunk bandwidth is needed. If the Adaptive Voice feature is not enabled for a channel with a "c" or "v" connections, VAD is always turned on for that channel. In order for a voice ("c" or "v") connection to use ADV, both ends must have ADV enabled with the cnfchadv command.

cnfchdl
Configures the dial type for a channel or set of channels. The dial type may be inband, pulse, or user-configured. The user-configured option allows non-default timing values to be used. The parameters associated with the cnfchdl command are timing constants used to ensure that signaling pulses are not distorted in time by transmission through the network.
•
•
•
If you select inband, the node assumes that the A and B bits are not used for loop-disconnect dialing. Therefore, any change in signaling bit status goes in a packet to the far end of the connection.
If you select pulse, the transmitting node waits (normally 72 ms) after an A or B bit transition for another transition to arrive. If a transition arrives, the new transition goes into the same signaling packet that is sent to the far end of the connection. This step increases the delay of the signaling transition across the network but decreases the amount of trunk bandwidth used for signaling.
If the default timings are not correct for the network, you must configure the options. The dialing type should be set correctly. If a connection-designated pulse is used for inband signaling, a greater than necessary delay across the network results. If a connection-designated inband is used for pulse signaling, the relative timing of signaling transitions may be lost and so distort the pulses.

cnfchfax
Configures a channel on a UVM for either FAX detection or FAX relay. If you enable FAX detection, the UVM suspends voice compression when it detects a FAX or modem tone on the channel. For the duration of the FAX, transmission takes place at 64 Kbps.
FAX relay is a mechanism for compression the FAX transmission rate across a network to 9.6 Kbps.
To view the current configuration, use the dspchcnf command.

Configures the amount of gain inserted by the IGX node for a given circuit line channel or range of channels. Gain can be configured between +6 dB and -8 dB. The input gain is inserted at the receive side of a voice card and is therefore applied before the signal is packetized by the card. The output gain is inserted at the transmit side of a voice card and is applied after the signal has been depacketized by the card. Gain is meaningless for channels that carry data.

cnfcond
Creates a conditioning template that specifies the bit patterns to be transmitted for each of the T1 and E1 timeslots and their A, B, C, and D signaling bits while the channel is in the failed state. Its purpose is to prevent the signaling bits from returning to the idle (on-hook) bit pattern during a channel failure and to force a known bit pattern (usually busy). If a connection fails and the template has been specified as the conditioning template for the failed connection, the data parameter in the template is transmitted in the channels timeslot, and the A, B, C, and D bits are processed according to the specified parameters.
A two-character sequence in the ID parameter field identifies the template. The Data Pattern field displays the pattern transmitted in the channels timeslot. The Signaling Pattern field displays the pattern transmitted in the channel's A, B, C, and D signaling bit positions. Each of the A, B, C, and D signaling bits are specified independently and may be held high or low or toggled to the on-hook condition for a short time then off-hook (the name of this latter action is a wink). You can control the timing of the bit-toggling by specifying the duration of winks in increments of 50 ms.
A typical failure response is for the node to:
1.
2.
3.

dspcons
Displays a summary of the connections on an IGX node. Table 6-29 shows the fields displayed in the dspcons screens.
The dspcons screen in Example 3 shows whether the Idle Code Suppression feature is enabled or disabled. The Idle Code Suppression feature provides a way to stop Fast Packet generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call. Traffic on the data network will therefore be reduced. Bursty data will be able to use this unused bandwidth.
On the dspcons screen, data connections show the letters ICS under the Compress field if the connection has idle code suppression enabled or not. This feature is supported only on IGX platforms in Release 9.2. It is supported only on the UVM and CDP/CVM cards. The UVM model E and CVM/CDP model B revision E firmware are required to use the Idle Code Suppression feature in Release 9.2.

Displays the status of the circuit line(s) and continues to display the status until you press the Delete key. While the display is on the screen, the status is automatically updated. The update frequency is one second for each circuit line being displayed. (For example, if only one line is displayed, the update frequency is once per second, if three circuit lines are displayed, the update frequency is once per three seconds.) Table 6-31 shows the connection type. The cnfchtp command must be correctly configured.

dspsigqual
Displays the configuration for the A, B, C, and D bit signaling qualifiers for all channels. The only parameter is the starting channel. You set the values for these signaling bits with the cnfrcvsig and cnfxmtsig commands. Note that these signaling bit states are different from the states during circuit alarm (signaling conditioning).
During normal operation of the voice circuit, the A, B, C, and D signaling bits may be held at a fixed value (0 or 1), inverted (I), or passed through transparently (T). For the direction of the signals, the transmit direction is towards the PBX or channel bank. Receive is from the external equipment.
